WHAT YOU NEED TO KNOW ABOUT BEARINGS

Understanding the differences in bearing seals is crucial. This product utilizes rubber seals that provide excellent debris protection while requiring minimal maintenance. However, it is essential to note that rubber sealed bearings may have slightly higher friction compared to metal shielded or PTFE sealed options.

DURABLE SEAL COLOR AND MATERIAL CHOICES

It's important to note the seal color is purely aesthetic and does not influence bearing performance. Additionally, these bearings are made from corrosion-resistant Stainless Steel, making them ideal for environments that demand durability against harsh conditions.
